UPDATE

 

In order to select desired rows you may use 'WHERE', 'OFFSET' and 'ROWS' parameters.
These parameters are also available on the result page in the command bar above the table.
The table is displayed using HTML forms as following:

 

- TEXT and BLOB columns are displayed as TEXTAREA forms with vertical scrolling enabled.
- All the other column types are displayed as TEXT forms.
Each TEXT and BLOB column has Radio button (1) placed beside the column name. Together with the checkboxes (2) it used to select the text or blob value to be zoomed.
The 'INSERT' bar placed under the table represents the table columns the same way as above and is used to insert new rows:

The following buttons resides on the control bar under the table:
Update, Insert, Zoom, Delete and Reset. Their names corresponds to the actions they produce.

Update command works when the user press Update button and only when one or more cells of the table were updated. If no cell was changed by the user, then the message will be generated, saying: "Nothing was changed".
A separate SQL query will be generated and executed for each row where data was changed. The rows are identified using PRIMARY KEY.
If the table has no PRIMARY KEY then al the columns of the table take part in the row identification, like this:
... WHERE col1='some data1' AND col2='some data2' ... .
It not always works correctly without unique keys.

LOW PRIORITY and IGNORE options are used in SQL query if the correspondent checkboxes are selected.

 In order to enlarge (zoom) any TEXT or BLOB values you must select the correspondent Radio button and the checkbox of the row  (next to the row number) to which the desired value belongs. The result of Zooming looks like this:

Data inside zoom window can be edited and updated by pressing 'Update' button. If 'Zoom Out' is pressed then all changes are ignored and the previous page will be displayed.
To delete some rows select them using checkboxes and click
DELETE.
LOW PRIORITY checkbox can be used with DELETE command.
Column bar is used to select the columns to be displayed.
If 'Preview' checkbox is selected, any query, generated by the program is displayed before to be sending for execution.
